In your code, assuming your regex is correct it matches *all* the time, thus
no matter how you get to members.php, you'll be redirected to login.php.
And do you really only want to let people access members.php directly after
visting login.php? How about if they login, go to the members page then go
somewhere else on your site, then try to go back to the members page and they
can't!
I would suggest that you use a more robust mechanism, such as sessions, for
allowing/denying access to certain pages.

If your login page does some sort of authentication and then either sets a cookie or a session variable or something you can check for that instead. If there's no valid login (cookie, session, whatever) then redirect back to the login page.

You can use JavaScript:
document.location="URL";
You can do that in an onClick (make sure that it's not a type submit, just a
type button if you're using a button).

Using the switch() function that I showed before here is what I have done...
login.php has the login form with an action of login1.php which is script
containing the case statement. It is just a script with no output until it
reaches its chosen header info.

Subject: [PHP] redirection rather than include()
This is a PHP newbie trying to figure something out.
I am creating a web-app which begins with a login page and goes through the
typical user/pass validation and upon success moves to a frameset where the
application will run. The action of the login form is act_login.php. In
that script I validate the user/pass and, upon validation, include() the
frameset script. However, I would rather redirect the browser to the
frameset script. In other words I want to progression to go like this...
login form --> successful login (determined by act_login.php) --> redirect
browser to app frameset
This scenario is probably swimming in technicalities, and I'm probably just
fine using the include() statement. However, I guess my overall question
is... is there a way to redirect the browser to a new URL (eg. php script)
inside something as simple as an if/then statement?
Thanks!

header("Location: index.php") should do the trick.
However, I'd recommend something more robust if avoiding duplicates is a big
deal. For example, if you're using sessions, you might have your addition
script set a confirmation variable using uniqid() and changing it after
updating the DB; if confirmation variable passed in the form submission doesn't
match the session variable, you can redirect them to the "Were you really
sure?" page. Alternately, depending on your data structure it might be easier
to simply insert a dummy record first and then use UPDATEs from that point
forward.
(The unique confirmation variable approach is also a good idea for security
purposes - otherwise if someone can guess the structure of your application,
they could do something funny like send an HTML email with a link to
/products/delete.php?ID=someID&Confirmed=yes to an admin, which would go
directly through without confirmation if they were logged in at the time.)

That's not the point. You should be writing the code such that you shouldn't need to make this kind of argument, at least for a simple HTTP-related issue anyway.

Yeah... I know what you and Jason mean.
I justed pointed out that it could work nicely... and I just tought of
that... I user header("location: ... ") on all my scripts and struggle to
put them before any output (that's not easy)...
I work on a e-commerce website (coding in ASP, but what can I do?) with
lots of JavaScript calls that in some cases are the heart of the operation,
and we never had any trouble or complaints with it.
I know that, the best way is to get your script running anywhere regardless
of what browser or OS people use, but is important too to use as much of
the technology as you can. Like HTML capable clients... in a recent pass,
that was a nightmare cuz half the people used the most outdated email
clients, but nowadays, almost every spam or corporate email I get, is HTML,
people who don't have HTML capable clients, hurry to get them. I won't even
get started with "Your browser isn't frames capable",
hehe. Javascipt is almost a standard and it is a great help in many cases
where server-side simply won't do the job. I don't know... I'm just
thinking here... maybe its all BS! :)

While I do utilise some javascript niceties in some of my work, I usually
only do it either when a) its an internal sytsem here at work and I know
everyone has the same system/software/setup or b) where its only an
enhancement and it wont affect the usability of the system if its not
there. Ill always try and use PHP and server side solutions before

that's a better way to think about it...
Altough... I still think that URL redirection should be something easier to
do... as it is something very usefull and very basic, if u think in the
concepts of WWW and surfing... going from one page to another is almost a
primitive... u know where I'm getting at?

use the javascript function, but also use as backup plan such as a link at
the bottom or even code at the top like this:
///
if (conditionals == true) {
header("location:home.html");
}
//

Re: [PHP] redirection to another page function
One thing that doesn't seem to have been considered is the use of the "refresh" meta tag. Whilst it depends on whether or not the browser is archaic (and let's face it, most people nowadays seem to be running at least version 4 of either IE or Netscape), it's something that can't be turned off (at least to my knowledge, I could be wrong) and workarounds can be supplied for instances when the browser doesn't accept the tag. This doesn't hinder programming too much, as you don't have to worry about sending output after headers, nor whether or not the browser has javascript enabled. Personally, I prefer to use the header() function, and it's ages since I've used this meta tag, though it's worth keeping in mind that old techniques can still be useful ;) James. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
